Answer 1

your app crash is not because of DATA_URL, it is because your image is too big to upload. try my code for your problem. You need to set quality below 50 and make sure reduce width and height. Use FILE_URI instead DATA_URL .

function capturePhoto() {
        // Take picture using device camera and retrieve image as base64-encoded string
    navigator.camera.getPicture(onPhotoDataSuccess, onFail, {
            quality: 30,
        targetWidth: 600,
        targetHeight: 600,
        destinationType: navigator.camera.DestinationType.FILE_URI,
        saveToPhotoAlbum: true,
        correctOrientation: true
    });
}
